Making Good Sounding Recordings
Dolby Noise Reduction Systems
Dolby B NR is the system used in most cassette tape decks to
reduce the background noise that is inherent in all cassette tapes.
Dolby Laboratories then developed an even more effective noise
reduction system, Dolby C NR, in response to the demand for in-
creasingly better sound quality from cassette tapes.
Both Dolby noise reduction systems operate by boosting sig-
nals during recording that fall below a certain input level. Dolby
B and C NR operate on the higher portions of the frequency
spectrum using what is called a ‘‘sliding band’’ technique. This is
because tape hiss is most prominent during the quiet, high fre-
quency portions of a recording. These same signals are then
reduced back to their original strength during playback, thereby
reducing the background noise by the same amount. In order to
operate only when necessary, the Dolby NR system has a varying
effect depending on the input level and frequency of the material
being recorded.
Dolby C NR is capable of reducing tape hiss by 10dB more
than Dolby B NR. In addition to its noise reduction function,
Dolby C NR has an anti-saturation network that lowers high input
levels before recording them and retums the signals to their
original strength during playback. This raises the high-frequency
saturation level of cassette tapes to allow you to record signals
that would normally cause distortion. This system raises the maxi-
mum output level of cassette tapes by more than 4dB at 10kHz.
The Dolby HX Pro System
Tape sensitivity is constantly changing as recordings are made
due to the biasing effect of high frequency audio signals. Dolby
HX Pro is a system that compensates for these undesirable fluc-
tuations during recording. It does not operate during playback, so
cassettes recorded with Dolby HX Pro can be played back on
decks not equipped with the system.
Note:
Dolby HX Pro operates independently of Dolby B and C NR, and
only during recording.
recording standby status.
Temporarily stop CD (or LP) play.
Rewind the tape to a position immedi-
ately preceding the portion you wish to
play.
Initiate play on the source com-
ponent and press the PLAY button
on the tape deck at the same time.
You can also use the CD Synchro
Recording function if the tape deck is
properly connected to an Onkyo CD
player bearing the FQ] mark.
MPX Filter for Recording FM Broadcasts
When recording FM broadcasts using Dolby NR, the 19kHz pilot
signal and the 38kHz subcarrier signal included in the FM broad-
cast signal can cause the Dolby circuitry to malfunction. This
deck is equipped with an MPX FILTER swilch to prevent this
from occurring. The MPX FILTER switch should be ON when
recording FM broadcasts using Dolby NR and OFF at all other
times.
Setting the Proper Recording Level
The recording level has an important effect on the sound quality a
tape will have when it is played back. A recording level that is
too high will cause distortion while one which is too low will
lower the signal-to-noise ratio resulting in a lape with excessive
“hiss noise.’’ It is particularly important to set the recording level
correctly with cassette tapes since they have a much thinner mag-
netic coating than open reel tapes. The thin coaling gives the tape
a comparatively low saturation level which can easily be sur-
passed if the recording level is set too high.
The recording level indicators feature a peak-hold function for the
indicators from -6 dB through +6 dB. This can come in handy
when setting the recording level.
CD Synchro Recording System
Once the K-611 is connected to a CD player bearing the RJ mark
(see page 13.), pressing the ® button of the CD player will
cause recording to commence automatically on the K-611.
1. Insert a cassette with the side to be recorded facing out.
2. Start the CD player.
3. Press the REC/PAUSE button to put the unit into the recording
standby mode. Adjust the input level. When the recording
level has been set, stop the CD player.
4. Start the CD player again, and recording will begin
simultaneously.
Notes:
1. Even if the CD player is stopped during recording, the cassette
deck will continue in the record mode.
2. If the cassette deck is in the recording standby mode when the
CD is put in PLAY, the deck will begin recording. When setting
recording levels, always start the CD first.
